Description

Technical Field

[0001] This invention relates to the field of die-cutting machine technology, specifically to an adjustable height-direction synchronous creasing die-cutting and printing machine. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, and mobile phone pads. They utilize steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. They are essential equipment for post-printing packaging processing.

[0003] Chinese Patent Publication No. CN108996296B discloses "a die-cutting machine, including an inner support plate, an outer support plate, a guide roller located between the inner support plate and the outer support plate, and a clamping device installed above the guide roller. The die-cutting machine also has a guiding device installed on one side of the guide roller. The guiding device has a guiding strip located near the guide roller. The die-cutting machine provided by the present invention has a guiding device. The set screw on the guiding device ensures that the angle of the guiding device remains consistent. Furthermore, the guiding device can strengthen the tension of the material on the guide roller and prevent the material from shifting, which would ultimately lead to a decrease in the neatness of the cross-section when the die-cutting machine is rewound."

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8An adjustable height-direction synchronous creasing and die-cutting printing machine includes: a machine body 1; a conveyor shaft 2; and a printing mechanism 3 for adjusting the distance between the printing shaft and the paper. The conveyor shaft 2 passes through the inner surface of the machine body 1 and is rotatably connected to the conveyor shaft 2. The printing mechanism 3 is located on the left surface of the machine body 1. The printing mechanism 3 includes a motor 31. The output shaft of the motor 31 is fixedly connected to a T-shaped shaft 32. The T-shaped shaft 32 is connected to a second T-shaped shaft 38 via a toothed belt 33. The arrangement of the T-shaped shaft 32 and the second T-shaped shaft 38 ensures that the toothed belt 33 will not be damaged while moving. To prevent motion interference, a T-shaped shaft 38 is fixedly connected to the left surface of the transmission shaft 2. A groove 34 is provided on the left surface of the machine body 1, and a slider 35 is slidably connected to the inner surface of the groove 34. The groove 34 effectively limits the slider 35, allowing it to slide stably. A gear 36 is rotatably connected to the left surface of the slider 35, meshing with a toothed belt 33. A printing roller 37 is fixedly connected to the inner surface of the gear 36, passing through the slider 35 and rotatably connected to it. A vertical plate 6 is fixedly connected to the left surface of the machine body 1. The front of the vertical plate 6... The surface has circular grooves 7 arranged in a linear array. An elastic conical rod 8 is slidably connected to the inner surface of the circular grooves 7. An L-shaped plate 9 is fixedly connected to the outer arc surface of the elastic conical rod 8. An elastic clamping knife 10 passes through the upper surface of the L-shaped plate 9. A clamping block 11 is fixedly connected to the upper surface of the slider 35. The clamping block 11 has a U-shaped cross-section and a trapezoidal groove on its inner surface. The clamping block 11 limits the elastic clamping knife 10, effectively ensuring that the elastic conical rod 8 can be stably clamped in the circular grooves 7. The inner surface of the clamping block 11 is slidably connected to the elastic clamping knife 10, and the elastic conical rod 8 passes through the conical rod... Composed of a spring, the spring provides elasticity to the tapered rod, allowing the tapered rod to be locked in the circular groove 7, thereby limiting the slider 35. This ensures that after the slider 35 adjusts the distance between the printing roller 37 and the conveyor shaft 2, the printing roller 37 can be made more stable. The elastic tapered rod 8 passes through the slider 35 and is slidably connected to the slider 35. Through the setting of the motor 31, T-shaft 1 32, T-shaft 2 38, gear 36, and toothed belt 33, the slider 35 can be adjusted according to the thickness of the paper, realizing the function of printing paper of different thicknesses at the same time, making the printing machine more stable. The inner surface of the machine body 1 is provided with a paper scraping mechanism 4, which is used to scrape the upper surface of the paper. The paper scraping mechanism 4 includes an arc-shaped fixing plate 41, which is fixedly connected to the inner surface of the machine body 1. A rectangular groove 42 is opened on the upper surface of the arc-shaped fixing plate 41, and a sliding hole 43 is opened on the inner surface of the rectangular groove 42. A movable rod 44 is slidably connected to the inner surface of the sliding hole 43. A horizontal plate 45 is fixedly connected to the upper surface of the movable rod 44. By setting the rectangular groove 42 and the sliding hole 43, the horizontal plate 45 and the movable rod 44 can be limited at the same time, ensuring that the movable rod 44 can only slide stably within the sliding hole 43. The horizontal plate 45 is locked in the rectangular groove 42. A scraping groove 46 is opened on the lower surface of the horizontal plate 45, and an elastic scraper 47 is slidably connected to the inner surface of the scraping groove 46. The elastic scraper 47 is composed of a scraper and a spring, and the spring provides elasticity to the scraper. The paper scraper 47 is designed to retract, scraping the uneven side of the paper while ensuring that the scraping mechanism 4 does not affect the normal printing process. A connecting plate 12 is fixedly connected to the lower surface of the movable rod 44. The front surface of the machine body 1 has slots 13 arranged in a linear array. An elastic lever 14 is slidably connected to the inner surface of the slots 13. The elastic lever 14 is composed of a spring and a lever. The spring provides elasticity to the lever, allowing it to be locked in the slots 13, ensuring that the horizontal plate 45 can be adjusted up and down. The horizontal plate 45 remains stable according to the thickness of the paper. The elastic lever 14 passes through the connecting plate 12 and is slidably connected to the connecting plate 12. With the setting of the elastic scraper 47, the scraping slot 46 and the arc-shaped fixing plate 41, the elastic scraper 47 scrapes off the uneven part of the upper surface of the paper, ensuring that the paper quality is significantly improved before printing. A punching mechanism 5 is used to punch holes in paper. The punching mechanism 5 is located on the right surface of the machine body 1. The punching mechanism 5 includes a punching plate 51, the inner surface of which is slidably connected to the right surface of the machine body 1. A vertical rod 52 is fixedly connected to the right surface of the machine body 1, passing through the punching plate 51 and slidably connected to it. A moving groove 53 is provided on the front surface of the punching plate 51, and a moving block 54 is slidably connected to the inner surface of the moving groove 53. The moving block 54 is limited by the moving groove 53, effectively ensuring its stability. A rotating shaft 55 is rotatably connected to the front surface of the perforating plate 51. A perforating disc 56 is fixedly connected to the outer arc surface of the rotating shaft 55. A friction plate 57 is fixedly connected to the front surface of the perforating plate 51. Through the friction between the friction plate 57 and the rotating shaft 55, the rotating shaft 55 can be rotated when the moving block 54 moves to the left, causing the perforating disc 56 to rotate and perforate the paper. The friction plate 57 is slidably connected to the outer arc surface of the rotating shaft 55. Limiting holes 15 are formed in a linear array on the outer arc surface of the vertical rod 52. An elastic limiting rod 16 is slidably connected to the inner surface of the limiting holes 15. Rod 16 is composed of a spring and a limiting rod. The limiting rod has a trapezoidal cross-sectional shape. The spring provides elasticity to the limiting rod, allowing the perforated plate 51 to be fixed and adjusted. The elastic limiting rod 16 passes through the perforated plate 51 and is slidably connected to it. An elastic support plate 17 passes through the upper surface of the perforated plate 51 and is slidably connected to it. The elastic support plate 17 is composed of a spring, a support plate, and a fixing rod. The fixing rod passes through the perforated plate 51 and is slidably connected to it. A spring is sleeved on the outer arc surface of the fixing rod, making the spring... The support plate provides elasticity, and the elasticity of the spring can keep the paper in close contact with the punching disk 56, thereby achieving a stable punching function. The upper surface of the elastic support plate 17 has punching slots 18 in a linear array. The inner surface of the punching slots 18 is slidably connected to the punching disk 56. Through the punching slots 18, the paper printed in batches can be punched stably. With the setting of the punching plate 51, punching disk 56, friction plate 57 and punching slots 18, the paper can be punched during the batch printing process, making it easy to cut the paper after the batch of paper is printed.

[0022] Working principle: Before printing paper, the elastic conical rod 8 is pushed towards the circular groove 7. The elastic conical rod 8 drives the L-shaped plate 9 and the elastic cutter 10 to move. When the elastic cutter 10 moves, its inclined surface is squeezed by the clamping block 11, causing the elastic cutter 10 to move upward. Due to the elasticity of the spring in the elastic conical rod 8, before the elastic cutter 10 has fully recovered, it is bounced back to the rear of the clamping block 11. After disengaging from the clamping block 11, the slider 35 moves up and down. The distance between the printing roller 37 and the conveyor shaft 2 is adjusted according to the required thickness of the printed paper. After the spacing is adjusted, the elastic conical rod 8 is pushed. The inclined surface of the elastic cutter 10 is squeezed by the clamping block 11. Through the elastic force of the elastic cutter 10 itself, the cutter is clamped in the clamping block 11, thereby limiting the slider 35. At this time, the paper can be printed normally. When the paper needs to be printed, the motor 31 is started. The output shaft of the motor 31 drives the T-shaped shaft 32 to rotate. At the same time, through the T-shaped shaft 38, the toothed belt 33 drives the toothed teeth to move. During the movement, the gear 36 is driven to rotate. The gear 36 drives the printing roller 37 to rotate, and the paper is printed. When it is necessary to process the uneven upper surface of the paper, after the elastic lever 14 is pulled out from the limiting hole 15, the connecting plate 12 is moved upward. The connecting plate 12 drives the movable rod 44 and the horizontal plate 45 to move upward. After they are disengaged from the rectangular groove 42, the paper is placed between the arc-shaped fixing plate 41 and the horizontal plate 45. Then, the motor 31 is started at the same time through the conveyor shaft 2. The output shaft of the motor 31 drives the conveyor shaft 2 to rotate through the toothed belt 33, which drives the paper to move. The uneven part of the upper surface of the paper is scraped smooth by the elastic scraper 47. When it is necessary to punch holes in the paper, the elastic support plate 17 is moved up and down to increase the distance between the elastic support plate 17 and the punching plate 51. Then, the moving block 54 moves in the moving groove 53. During the movement, the friction between the friction plate 57 and the rotating shaft 55 drives the rotating shaft 55 to rotate. The rotating shaft 55 drives the punching disc 56 to rotate. At the same time, the elasticity of the elastic support plate 17 clamps the paper between the punching disc 56 and the punching groove 18. When the punching disc 56 rotates through the friction plate 57, it punches holes in the upper surface of the paper.
